Fatigue Crack Growth Characteristics on The Weld Joint of Bimaterial
초록
This paper was conducted the fatigue crack growth test on the base metal and weld joint of bimaterial(carbon-stainless steel), carbon steel and stainless steel. As the result, the fatigue crack growth rate of weld joint on the stainless-stainless steel is faster than stainless base metal, and weld joint on the carbon-carbon steel heat affected zone is slower than carbon base metal. And fatigue crack growth rate of carbon-stainless steel weld joint and heat affected zone is similar to the behavior of stainless base metal. In conclusion, weld joint of bimaterial is stable in the fatigue crack growth behavior.
